The attached is a second recipe; this one builds a linux->cygwin
gcc-4.5.0 compiler with sysroot support, as well as enabling libgomp.
It differs from the "native" cygwin 4.5.0 compiler in the following ways
(other than the obvious, of course):
graphite is not enabled
lto is not enabled
To use this recipe, I recommend (a) modifying the various settings at
the top as needed (b) cut and paste small sections (10 lines or so) into
a terminal -- rather than attempting the "run" the recipe as a script.
It's not that polished.
Using the cross-compiler generated using this recipe, the "sysroot"
support in libtool-2.2.11a passes its own tests (the cross-compiler
built using the previous recipe, because it had no sysroot support,
caused those tests to be skipped).
I was able to rebuild cygwin itself using this compiler with no issues
(except those related to -Werror; there are a number of files in cygwin
that cause alias warnings).
